Common Applications and Problem Resolution

This ABS wheel speed sensor is specifically compatible with Subaru Legacy and Outback vehicles, making it a suitable replacement part for maintaining ABS system accuracy. It addresses issues such as:

Installation requires bolting the sensor securely to the wheel mounting location using the existing bolt hole. Ensure the connector is properly aligned and fully engaged to avoid electrical issues. The included wiring harness length of 32.5 inches allows for flexible routing, but care should be taken to avoid sharp bends or contact with moving parts. Since mounting hardware is not included, reuse the original bolt or source an appropriate replacement.
